But, im not saying some couldnt have gotten past them and into the sending units and into my system, but i couldnt imagine it would be much...... but that may be all it takes?

If thats the case, what the hell can i do to prevent this? The tank allways has air in it, so could it be passing it on from thare? Should i keep the tank drained at night when it sits? or maybee instead of installing the sending units directly into my "T" fitting, i could branch it off and have it sit higher than the rest of the unit.... idk.

idk, im sure some water can get past those SMC traps, but i just cant imagine much. This kinda blows, because i cant see much way of fixing the issue, short of trying new water traps...?

Thanks doug,


Taylor
That is a tough call, All I can suggest is run a small 90 elbow off the T so the sensor has its but up in the air, any water that gets in can drain out from gravity.

If you get time check your sensors, you may only have one bad one, that is causing all of these damn problems! lol

Re: Issues with my digital gauge kit



That is with ONLY one bad sensor connected to the gauge port, and NO other gauges connected.

Re: Issues with my digital gauge kit

So, do you think these sending units are salvageable?

Do i need to pull them out, and let them drain or something?

idk. What your saying makes sence tho. My tank sending unit was the first to go out, it was closest to the tank, and if any moisture would have gotten by the filters, or if condensation would have filled in the tank from a sit over night, that sending unit would see it first.

The order the gagues went out, pretty much in the order of their distance from the tank....

sooo, im gonna guess that this wont be covered under any warranty?

I would start with a volt meter to find the bad unit(s) then remove them from the system for now and hope they did not damage the Gauge unit.

Let them sit thread side down or hang from the wire for a few days to see if that helps. Easy to test just apply 12V to the RED and BLACK then attach a volt meter between BLACK and WHITE if the sensor is ready to go back in it will read under 1VDC

Is there a full 12V going to the Gauge and or sensor?

If you look in my video under voltage will cause weird fluctuations.

Did you measure the sensor with it disconnected from the gauge?

If you can disconnect every gauge and re connect the known good units one at a time (only one at a time) and look for anything odd. They should read 0

the sender is being measured while its unplugged from the gauge.

i try to plug one in at a time, to isolate the gauge that is acting up, and each individual gauge reads the same as it would when they were all plugged in together.

someware between 17-25psi.

when the others are unplugged and only one is in, the rest of the gauges read "---" than the one that is plugged in reads 17-25psi, depending on what corner i go with.

Re: Issues with my digital gauge kit

Nothing but problems today.

I think i may have isolated what was causing my inital problem, but i may have discovered more problems.

When i got home today, i drained my tank, and started my hunt for the bad sending unit over again. I was able to un-plug my sending unit for my tank pressure, and it made my other gagues read "000" again, which i was really really happy about. It still sucks super ass that this is gonna be my 3rd replacment tank sending unit.

So, after that i went and put my plugs back together for all my sending units and grabbed some zip ties to connect them to their mounting points again, and wouldnt ya know it, the gauges start acting up again.... Now one is reading 298 psi, and the others are reading between 4 and 29.

So i start to wiggle the wires at each one, while my wife watches the gauges, and sure enough they go in and out from working correctly to, working like complete shit.

Come to find out, every one of my connectors on the ends of my wires are loose, and the white wire for each one is almost pulled out. My right rear one is completely pulled out, all 3 wires.

So, now ontop of having my 3rd bad tank sending unit, i also have 5 wireing harnesses that are ready to fall apart. All the terminals have corrosion in them also, espically the ones that are just barely toutching the metal.


what to do now?

That tells me there is water in the Tank sending unit again,

Hang it from its wire for 2 days or out in the sun to drain out well, and try it again.

You will laugh but hell try a small water trap just before the tank sensor lol

Re: Issues with my digital gauge kit

hey kris or jeff, is this a problem that everyone is going to have to worry about? i'm really wanting to get these gauges but i'm kind of waiting to see the outcome of taylor's. it don't seem like the kit will hold up if he is running 2 water traps and the amount of water makeing it through is messing up the sending unit. that is assuming that water is the problem.

Taylor is the only one that has mentioned this problem. If there is anyone else reading this thread that has our gauge, PLEASE POST, regardless if it's good or bad. If there is any problems with an AVS brand product, rest assured that you will be taken care of.

Re: Issues with my digital gauge kit

Taylor:

1. Please make sure that the tank pressure sender is mounted high enough on the tank so water does not collect in the sender. Also, installing an elbow (on a higher positioned port) sounds like a good idea.

2. The wires were obviously pulled out of the crimps. These are built pretty damn solid but if you yank on them of course they will pull our. Since you have this problem compounded by corrosion the best thing would be to cut off all of the plugs and solder and shrink tube the senders to the harness.

3. Out of curiosity, back on posts #17 & #18 when I suggested that you check the pins in each harness for alignment and contact... you said you did. How come you didn't catch the corrosion or the pulled out wires then? lol! oh well... I'm just hoping that you didn't short those bare wires together or to ground. No telling what would happen if the +12V or -12V wires touched the input wire to the gauge.

So now the problem can be from moisture, but then again, it could be from a short from the wires that were pulled out. Anyhow, I would strongly suggest to any of our customers to generously slather some DIELECTRIC GREASE into and around the plugs of the harness and sender. We will also look into building these with waterproof plugs on our next run of gauges.

Taylor, please let them hang dry as instructed by Doug then get these babies soldered up and let me know hot it goes. No matter what, we'll get this squared away for ya!

Re: Issues with my digital gauge kit

um taylor if you are up for it, i would install weather pack connectors on these, i dont quite understand why they aren't installed from the get go but it might be a way for AVS to grow and better their products. I'm not sure where you can find weather-pack connectors, MAYBE Autozone can order them, or i know you can find them online. Weather-pack is what GM, Ford, Dodge, pretty much every auto maker uses on any connector that could possibly be susceptible to water, just my .02 and idea, but i think it would be the way to go.

1. I am going to let my tank sending unit dry out this weekend, and i am going to pick a new mounting point for it, so its higher than the tank. Im hoping that will take care of it.

2. I have my old boss at the local stereo shop looking at soem quick connectors like this for me to solder in place instead of the connectors that came with them. Im hoping this works. If not , iwill hard wire them this year, and look for a better laternative to that this winter when i pull my bed off.

3. I didnt notice the corrosion because i was only looking at the PIN or male side of the harness, and those still look clean, the femalse side, looks very very corroded. That and, i was looking at them while i was in the garage, with a flashlight, because my truck was layed out at the time, i just did a quick check to see if any pins were crossed, i was more than 100% positive that they wernt, because the kit worked good initally, and then slowly went and took a sh!t on me. The corrosion is hard to notice on the plugs when their on the vehicle, it wasnt untill the plug completely fell off of that other wire and was in my had that i noticed the corrosion and quickly checked the other units for that. I puled the power on my main fuse that was giving everything power as soon as i noticed the wires pulled out. I dont believe anything was affected, because i hardwired it last night for a quick check, and put power back to it, with the tank sending unit pulled, and the gauges worked properly again.



I think everything is going to work out tho. I do believe i will have one bad sending unit, which would be my tank pressure one, just because it has been out for so damn long, idk if it will beable to bring back.


Ill let you know towards the end of the weekend if my tank sending unit starts working or not...

thanks

Here ya go man,

http://www.homedepot.com/webapp/wcs/...ctId=100027474

1/4" double female at your local home depot.

The weatherpack fittings are nice but best bet is solder and heat shrink.

The back blue cover does come off the Gauge (press fit) simply wiggle with channel locks. and the old wire is plugged into the circuit.

You can splice your wires inside the sensor housing for a clean water tight install.

Re: Issues with my digital gauge kit

OK.

I let that sending unit dry out all weekend. I re-installed it in a remote location, and its working so far so good.

I relocated the sending unit up higher than the tank with a lead of hose on it, that i could monitor for moisture.

I suggest for anyone that buys this kit to make sure they either really know that they system has absolutely no moisture, or right off the bat, they install their sending untis remotely, higher than everything, with a hose they can monitor moisture. I also reccomend that you right off the bat replace the wire ends, mine had very minimal wear, and i remembered to have some slack tied into the wires, adn they still all came loose and caused problems. Its a simple fix to hardwire them or to put your own ends on them also.



This has been a HUGE pain in the ass, but it appears to all be good now, i hope not to have any huge issues for the rest of the year with this. I need to go through and replace all the ends on the wires, because those are acting up now.

Re: Issues with my digital gauge kit

like i said mine are working good..with no pressure the drivers side front reads 0-1 psi, the passenger front reads 2-3psi and the tank is off by about 5 psi but that doesnt really bother me..i can still keep my ride height figured out..oh and i dont have gauges on the rear
